Assume that an exhaled breath of air consists of 74.8% N2, 15.3% O2, 3.7% CO2 and 6.2% water vapor. (a)
(a) If the total pressure of the gases is 0.985 atm, calculate the partial pressure of each component of the mixture.
(b) If the volume of the exhaled gas is 455 mL and its temperature is 37oC, calculate the number of moles of CO2 exhaled.
(c) How many grams of glucose (C6H12O6) would need to be metabolized to produce this quantity of CO2? (The chemical reaction is the same as that for combustion of C6H12O6.
